Jordin Sparks lost 50lbs to improve her health.

The 'One Step At A Time' hitmaker, who now fluctuates between 155 to 161lbs, decided to lose weight because she was fed up of feeling sluggish and unwell.

She said: ''I had gotten really sick. And I was about to celebrate my birthday and I was like, 'I should be in the prime of my life right now. I shouldn't be feeling like this. I really need to make my health a priority'.''

The 24-year-old singer, who lost weight by changing up her diet and adding more exercise into her lifestyle, insists she never felt pressurised into shedding the pounds because she was happy with how she looked beforehand.

She explained on the 'Today' show: ''I was comfortable with how I looked before, but it was about really focusing on become healthier.

''And then my body changed, which was awesome. But it wasn't about being a size zero, or anything like that.''

Jordin, who has been dating Jason Derulo for over three years, hopes she can encourage other women to look in the mirror and love their bodies as well.

She said: ''I know that there are some women who struggle to even look themselves in the mirror. And I hope that those women who are struggling can watch this and go, 'You know what? I'm OK with who I am. And I'm beautiful in my own way'.''
